However, Dr Pullen and his team present evidence that plant growth is actually «sink - limited,» meaning that genetic regulation and cell division rates have a much bigger role in controlling plant growth than previously thought: «We are proposing that plant growth is not physically limited by Net Primary Productivity (NPP) or the environment, but instead is limited genetically in response to these signals to ensure they do not become limiting.»

«Being in the Mix Lab (special labs that have researchers from different disciplines mixed together) at ITbM, I was able to talk to an organic chemist, Masakazu Nambo, who suggested the use of triarylmethane compounds for cell division inhibition in plant cells,» she continues.
We started this research about 3 years ago, but we were fortunate to be able to identify a triarylmethane compound that can rapidly inhibit cell division in plants,» he continues.
«Our palladium - catalyzed sequential arylation reaction has been highly useful to rapidly synthesize a variety of triarylmethanes to be used for testing their effect on the cell division in plants,» says Nambo.
This improves the performance of the mitochondria in their role as the power plants of the cell, thus ensuring that enough energy is available for a complex event like cell division.
Thus, it has been considered that if there is a way to control cell division in plants, this will lead to the control of plant growth in a range of plant species.

«We saw that chem7 had hardly any effect on the shapes of the cells and tissues, thus, suggesting that chem7 stops cell division in plant cells, but does not cause any severe damage to the shapes,» describes Ueda.
«chem7 rapidly stops cell division and plant growth without causing drastic damage to the shapes or functions of the cells.»
It thus seems quite likely that this new signaling path also links the performance of the cellular power plants and cell division in human cells,» says Meisinger, who now plans to analyze these mechanisms in tumor tissues.
Although various compounds that can control cell division in plants have been explored in the past, they have mainly resulted in damage to the plant shape or irreversible inhibition of cell division despite removal of the compounds.

Controlling cell division is an important first step in the development of new organs in plants.
Cell division in plants is governed by a physical law.
